Abstract

The invention relates to an oil-electric hybrid hot-chamber die casting machine injection system, which comprises a melting pot sleeve, an injection rod, a servomotor controller and a hydraulic pressurizer, a servomotor drives the injection rod in order to control the injection speed in the process of injection, and the hydraulic pressurizer cooperates with the servomotor controller to drive the injection rod in order to control rapid pressurization in the process of injection. The injection speed is controlled by the servomotor, the servomotor controls multi-stage slow speed, uniform acceleration, multi-stage high speed, speed reduction and braking in the process of injection, and can realize the multi-stage stepless regulation of the injection speed, consequently, the flashless function of die casting is realized, and high-quality net-shaped products can be shaped. Meanwhile, a hydraulic system is utilized to carry out pressurization, pressurization is independently controlled, which can help to shorten the pressurization time, consequently, a large motor does not need to be adopted in order to achieve high increased pressure, and thereby the cost is reduced.

Description

technical field [0001] The invention relates to a hot-chamber die-casting machine, more specifically, to a novel injection system of a hot-chamber die-casting machine mixed with oil and electricity. Background technique [0002] At present, the injection systems of traditional hot chamber die-casting machines at home and abroad generally use hydraulic pressure as power to realize pressure casting of metals (aluminum alloys, magnesium alloys, copper alloys, etc.). In the material pot of the die-casting machine, the hydraulic system drives the injection rod forward, and pushes the alloy liquid to go slow and high speed. In the process of slow speed and high speed, the speed control is required to be stable and without fluctuations. [0003] While the injection rod is decelerating, the hydraulic system drives the pressurization system to push the injection rod to realize pressurization and shrinkage during the metal cooling process, so that the inside of the metal product is de...
